RAILWAY-TRACK STRUCTU RE.

SPECIFICATION forming part of Letters Patent No. 716,353, dated December 16,1902.

Application filed July 29, 1902.

To a, whom it 77mg concern:

Be it known that I, CONSTANTINE B. VoY- NOW, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certain Improvements in Railway-Track Structures, of which the following is a specification.

My invention relates to railway-track structures such as are employed at the intersection of diiferent lines of rails'such as crossings, frogs, and the like-in which the wear due to passing car-wheels, which is very great at these points, is taken upon a hardenedsteel wear-plate, which wear-plate may be removed when worn and replaced bya new one.

The principal object of my present invention is to provide a track structure in which the wear-plate can be renewed without the necessity of tearing up the surrounding pavement of the street; and, furthermore, to provide satisfactory, reliable, and efficient means for detachably securing the wear-plate to the body portion of the structure in such a manner that the Wear-plate-securingmembers may not be accidentally lost through or into the body portion of the structure during the operation of detaching or renewing the wear-plate.

To these and other ends, hereinafter set forth, my invention, stated in general terms, comprises a track structure consisting of a body portion, a wear-plate having on its upper surface a recess or slot adapted to receive a nut or wedged key which secures a clamping-bolt for drawing the wear-plate firmly down to the body portion, thesaid clamping-bolt being accessible from the top of the structure, and which clamping-bolt is supported so that it may not be accidentally, or is not necessarily, lost when caused to disengage the parts which it connects.

The nature, characteristic features, and

scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming a part hereof, and in which I Figure l is a top or plan view of a structure embodying my invention with the wear-plate erial No. 117,485. (No model.)

the same. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is a side view of Fig. 1, with the wear-plate and its clamping-bolts removed.

In the drawings, 1 is the body portion or base of the structure, and the wear-platosecuring bolts 2 2 do not pass entirely through it. If they did so, in the operation of coupling and uncoupling the parts the securingbolts could easily drop through or into the body portion of the structure, thus making necessary the removal of some of the street paving for the proper readjustment of the parts, and thereby defeating one of the principal objects of this invention.

In the top portion of the base-piece 1 there are side openings 10 10 for the reception of the wear-plate-securing bolts 2 2, which openings are closed at the bottom but open at the top, and are also open on one side to the outside of the base-piece 1, so that each bolt 2 can he slipped sidewise into the opening 10 to its proper place with its head supported by the bottom of the opening. When the clamping-bolts are thus in position, the wearplate 6 can be readily dropped over them, with the upper ends of the bolts projecting upwardly through it. The wedged keys 8 8 can then be applied to the bolts 2 2, and the wearplate 6 will thus be drawn down securely to its proper position. The upper face of. the base 1 is adapted to receive the detachable wear-plate 6, and the latter is provided with a recess or slot 7, the lower Wall of which is engaged by the wedged key 8.

The principal feature of the invention is that the bolt 2 can be properly manipulated from the top of the structure, so as to release the parts which it connects, and, conversely, to connect the same without disturbing the street pavement and without the possibility of accidentally losing the bolt itself by permitting it to fall through or into the structure. Of course the number of clamping-bolts may be any number that may be deemed most desirable.

The recess or slot 7, while wide enough at one place to admit the upper part of the bolt 2, is, however, no Wider throughout the remainder of its length than to allow the wedged key 8 to slide lengthwise therein. This re- IOO cess or slot is therefore quite narrow, and the wearing-surface of the wear-plate is very little reduced or impaired thereby.

Use may be made of a filling 9, which preferably consists of a metal having a low fusing-point applied in a molten state, and this soft metal may not only run in between the base and the wear-plate, but it may also be applied about the clamping-bolt 2 and its wedged key 8, and in that case if applied after the key is driven home it will lock it fast and prevent any retrograde movement thereof.

It will be obvious to those skilled in the art to which my invention relates that modifications may be made in the details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings.

Ido not claim as my invention a track structure comprising a base and a wear-plate and a clamping-bolt for securing said wear-plate to said base accessible from the top of the structure and a liner interposed in a molten state between said wear-plate and base, as that is the subject-matter of an application for Letters Patent of the United States for improvement in railway track structures, dated this day, by Victor Angerer, of Ridley Park, Delaware county, Pennsylvania; but

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a track structure,of a base portion having an undercut opening in its side extending to the top thereof, said opening being closed at the bottom, with a wearplate having a hole, a headed bolt extending upward through the opening in the base portion and through the hole in the wear-plate, a fastening for the bolt in a recess in the top of the wear-plate, and a liner interposed between the wear-plate and the base, substanwear-plate and having its key contained within the recess or slot of the wear-plate, and a liner interposed in a molten state between said base and said wear-plate and surrounding and locking the key, the opening in the base for the reception of the clamping-bolt being closed at its bottom and open on one of its sides to the outside of the base, substantially as described.

3. A track structure comprising a base and a wear-plate, an opening in said base for the reception of a clamping-bolt, an opening in said wear-plate for the reception of said clamping-bolt, a recess or slot at the upper end of said opening in said wear-plate for the reception of a wedged key, a clamping-bolt passing through said openings in the base and wear-plate and having its key contained within the said recess or slot of the wear-plate, the said recess or slot, while wide enough at one place to admit the said bolt, being contracted in width throughout the remainder of its length to be no wider than will permit the said key to slide lengthwise therein.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CONSTANTINE l3. VOYNOW.
